Prof. Amit P. Sheth Abstract: While Bill Gates, Stephen Hawking, Elon Musk, Peter Thiel, and others engage in OpenAI discussions of whether or not AI, robots, and machines will replace humans, proponents of human-centric computing continue to extend work in which humans and machines partner in contextualized and personalized processing of multimodal data to derive actionable information. This talk describes how maturing towards the emerging paradigms of semantic computing (SC), cognitive computing (CC), and perceptual computing (PC) provides a continuum through which to exploit the ever-increasing and growing diversity of data that could enhance people’s daily lives. SC and CC sift through raw data to personalize it according to context and individual users, creating abstractions that move the data closer to what humans can readily understand and apply in decision-making. PC, which interacts with the surrounding environment to collect data that is relevant and useful in understanding the outside world, is characterized by interpretative and exploratory activities that are supported by the use of prior/background knowledge. Using the examples of personalized digital health and a smart city, we will demonstrate how the trio of these computing paradigms form complementary capabilities that will enable the development of the next generation of intelligent systems.

It is our pleasure to invite you to ColaHacks, USC's first student hackathon, taking place Saturday, April 14th from 9am-9pm at the Zone at Williams-Brice Stadium. Participation is limited to 160 students so if interested, please register as soon as possible at www.colahacks.com. Registration is free and open to all undergraduate/graduate students currently attending USC. Major League Hacking (MLH) defines hackathon as an invention marathon. Anyone who has an interest in technology attends a hackathon to learn, build and share their creations over the course of a weekend in a relaxed and welcoming atmosphere. You don’t have to be a programmer, and you certainly don’t have to be a Computer Science major. All you need is a passion for solving unique challenges our generation faces and a love for technology. ColaHacks gives students almost 12 hours to work on a project they feel betters Columbia, SC in some way; be it an app, website, or any other technology. Teams of students (1-4) will then demo and present their ideas to judges for the chance to compete for cash prizes as well as other gifts and awards. There are many reasons you should want to attend a hackathon, but here are just a few benefits that ColaHacks will be offering:

• Free catered food and refreshments all day long
• Awards of up to $750, as well as gifts such as Google Homes, Amazon Echos, 3D printing pens and more!
• Door prizes and giveaways
• Opportunities to network with students and technologists in the local area
• Growth in technical skills, presentation abilities, and leadership.
• Access to engineers and recruiters from top local tech companies, including 52Inc, Swampfox, Boeing, AgFirst, and more
• If you have any questions, feel free to reach out to the organizing team at colahacks@gmail.com. Make sure to register soon at: www.colahacks.com. Thank you for your time, and we look forward to seeing you on April 14!

Best, ColaHacks 2018

THESIS DEFENSE Author : Srujana Bollina Advisor : Dr. Gregory Gay Abstract Masking occurs when one condition prevents another condition from influencing the output of a Boolean expression. Logic-based adequacy criteria such as Multiple Condition Coverage (MCC) are designed to overcome masking at the within-expression level, but can offer no guarantees about masking in subsequent expressions. As a result, a Boolean expression written as a single complex statement will yield test cases that are more likely to overcome masking than when the expression is written as series of simple statements. Many approaches to automated analysis and test case generation for Java systems operate not on the source code representation of code, but on the bytecode. The transformation from source code to bytecode requires simplifying code elements, introducing the risk of masking. We propose Bytecode-MCC, designed to group related Boolean expressions from the bytecode, reformulate the expressions into a single complex expression, and produce test cases satisfying each combination of conditions in the constructed expression. Bytecode-MCC should produce test obligations that—when satisfied—are more likely to reveal faults in the program logic than tests providing coverage of existing criteria over the simplified bytecode. A preliminary study has hinted at the potential of this approach. However, Bytecode-MCC is more difficult to achieve than Branch Coverage, and means of increasing coverage are needed to truly test the fault-detection potential of this technique. We propose methods of improving Bytecode-MCC coverage through automated generation that we will explore in future work.

DISSERTATION DEFENSE Author: Mark Daniels Advisor: Dr. Csilla Farkas Abstract An individual’s healthcare data may be the most private information a person possesses. Current regulations, such as the Health Insurance Portability and Accountability Act of 1996 (HIPAA), safeguard patient data by assigning a sensitivity level to data items. However, this approach is limited when domain knowledge is used to infer additional patient data. In our research, we investigate privacy violations occurring when non-confidential patient data is combined with medical domain ontologies to disclose a patient’s protected health information (PHI). We developed a framework that detects privacy violations and eliminates undesired inferences. Our inference channel removal process is based on controlling the release of the data items that lead to undesired inferences. These data items are either blocked from release or generalized to eliminate the disclosure of the PHI. We first developed an exhaustive framework to disrupt the undesired inferences, then improved on the methods using a heuristic-based approach. Our privacy model includes traditional security assessments (i.e., HIPAA) as well as considering safety and patient privacy preferences. We developed a graphic user interface that allows patients to control the release of their data. We also visualize the inferred data using the healthcare domain knowledge.

DISSERTATION DEFENSE Author : Xian Wu Advisor : Dr. Jenay Beer Abstract Maintaining health and wellness while aging-in-place independently is crucial for older adults. Telepresence technology can be potentially beneficial for this target population to stay socially connected. However, this technology is not specifically designed for older adults. For this target population to adopt such technology successfully, it is important to ensure that they do not experience usability barriers. This research uses HCI/HRI concepts and technology design principles for older adults to design, develop and test telepresence user interfaces (UI). This addresses the following research questions: 1): What are the essential usability and privacy-enhanced features needed to inform the design and development of a new telepresence UI for aging population? 2): Is the new telepresence UI perceived as more usable and private by older users compared to traditional telepresence UI design? Thirty older adults aged above 60 in South Carolina and Georgia participated in a within-subjects user-testing with two UIs: 1) a generic UI called Presence designed based on currently available telepresence robots; and 2) a privacy-enhanced usable telepresence UI named InTouch. Participants tested both UIs in a virtual home environment developed in Unity. Results of this study suggest that older adults perceived InTouch to be more usable and private. This study provides insight on what usability and privacy features are critical for the aging population to use such telepresence technology. By investigating the design of telepresence robots for older users, and applying those findings to design recommendations, the final goal is to improve the ease of use and privacy level of telepresence robots – not only for our target users, but for all users who wish to enhance their social connectedness.
